Groupe Crossotides, Lac.? Gen. Humimeti affinis, Corpus subtrigonum. Caput retractile, inter antennas 
parum concavum ; frons brevis et lata; oculi subgrosse granulati, lobo inferiori paullo transverso. Antenne 
tenuiter filiformes, subnude, corpore paullo longiores ; scapo sicut in Estol¢s et Oreoderis, mediocri, oblongo- 
clavato, basi intus sinuato-angustato ; articulis 3 et 4 sequalibus, mediocriter elongatis, subcurvatis, apice 
subtus leviter incrassatis, ceteris gradatim decrescentibus. Thorax valde transversus, post medium 
dilatatus ibique lateribus angulatis vel late tuberculatis, deinde antice valde angustatus, tuberculo obtuso 
juxta angulum anteriorem. LElytra brevia, a basi usque ad apicem angustata, apice conjunctim rotundata. 
Pedes mediocres, femora sat crasse clavata; tibie intermedie extus prope apicem sinuate ; tarsi breves. 
Pro- et mesosternum planissima et latissima. Coxe sat exserte; acetabula antica extus late angulata ; 
intermedia late aperta. 
A genus having no near affinity with any other American form of Lamiide, except 
perhaps the genus Anoreina, Bates. In facies it most resembles certain undescribed 
African species allied to Frea and Dichostates ; but it differs from the group “ Crossotides,” 
to which these belong, in having a distinct sinus on the outer edge of the middle tibiz. 
From the American group “ Anisocerides,” with which it agrees in the gaping outer 
rims of the anterior and middle acetabula, it differs in the form of the scape, which 
is that of the great majority of the Estolides, Apodasyides, and Pogonocherides of 
Lacordaire, and of the genus Oreodera. The head is strongly retractile as in the 
Crossotides, the mouth resting in repose on the broad prosternum between the prominent 
anterior haunches. ‘The position of the genus seems to be between the African 
“ Crossotini ” (especially Humémetes) and the American “ Oreoderini,’ through the genus 
Anoreina of the latter group, which differs from Xenofrea in its ciliated and bristly 
antenne, the sharp notch nearer the middle of the intermediate tibie, and the acetabular 
suture of the anterior haunches nearly closed as in Oreodera. 
Two'other species from Equatorial South America belong also to the genus *.
